Goal: Capstone Dashboard
Tahapan: - Preprocessing - Cleansing - Perubahan tipe data - Feature Engineering - Aggregasi data - Buat Tooltip - Visualisasi Data - Buat visualisasi interaktif - Web dashboard
Kita akan coba mengeksplorasi kembali data Pakistan Largest Ecommerce Dataset menggunakan package dplyr! Mari kita baca terlebih dahulu data kita:
# read data
data <- read.csv("Pakistan Largest Ecommerce Dataset.csv", stringsAsFactors = TRUE, encoding = "latin1")
# cleansing data
data_clean <- data %>%
select(
#membersihkan yang tidak perlu
-c(increment_id, sales_commission_code, Working.Date, BI.Status,MV, Year, Month, Customer.Since, M.Y, FY, X, X.1, X.2, X.3, X.4)) %>%
mutate(
#ngubah tipe data
created_at= dmy(created_at),
sku= as.character(sku),
#nambah kolom
month= month(created_at, label = FALSE, abbr = TRUE),
year= year(created_at)
) %>%
#gantii nama kolom
rename(
c(product_name = sku, category_name = category_name_1)) %>%
filter(
#filter hanya menggunakan tahun 2017
year(created_at) %in% c(2017),
category_name != "\\N",
grepl("_", product_name) # filter nama produk yang tidak adaa "_" atau kelihatan seperti barcode
)
